Heidi Klum did all the talking yesterday when she filed for divorce from hubby Seal -- and when we caught him last night at LAX, the singer passed on the opportunity to do some talking of his own.
Heidi cited "irreconcilable differences" in her divorce petition filed in L.A. County Superior Court. The couple has a post-nup in place to divide their assets, so the big issue will be custody. Heidi is asking for joint legal custody of their four children, but she wants primary physical custody ... with Seal getting visitation rights.
We asked Seal if he knew the filing was imminent and whether he planned to stay friends with Heidi through the process ... no answer.
